I had a great time at ICOTS9. Academic conferences are a bit of a lottery, but ICOTS is two for two for me. Both ICOTS8 and ICOTS9 were winners – enjoyable, interesting and inspiring.  I’ve just returned from ICOTS9 in … Continue reading →

Frank de Libero writes: I read your Chance article (disproving that no one reads Chance!) re communicating about flawed psychological research.

Stan World Cup update

The other day I fit a simple model to estimate team abilities from World Cup outcomes. I fit the model to the signed square roots of the score differentials, using the square root on the theory that when the game is less close, it becomes more variable. 0. Background As you might recall, the estimated […] The post Stan World Cup update appeared first on Statistical Modeling, Causal Inference, and…

Sometimes I feel (some) need for speed

I’m the first to acknowledge that most of my code could run faster. The truth of the matter is that, in essence, I write ‘quickies’: code that will run once or twice, so there is no incentive to spend days or hours in shaving seconds of a computation. Most analyses of research data fall in […]

It is so random! Or is it? The meaning of randomness

The concept of “random” is a tough one. First there is the problem of lexical ambiguity. There are colloquial meanings for random that don’t totally tie in with the technical or domain-specific meanings for random. Then there is the fact … Continue reading →

Hurricanes/himmicanes extra:  Again with the problematic nature of the scientific publication process

Jeremy Freese has the story. To me, the sad thing is not that people who don’t understand statistics are doing research. After all, statistics is hard, and to require statistical understanding of all quantitative researchers would be impossible to enforce in any case. Indeed, if anything, one of the goals of the statistical profession is […] The post Hurricanes/himmicanes extra: Again with the problematic nature of the scientific publication process…

Creating a handout from beamer slides

I’m about to head off on a speaking tour to Europe (more on that in another post) and one of my hosts has asked for my powerpoint slides so they can print them. They have made two false assumptions: (1) that I use powerpoint; (2) that my slides are static so they can be printed. Instead, I produced a cut-down version of my beamer slides, leaving out some of the…
